Personally, I think that’s highly likely.
The whole extended family has been on Vitamin D and zinc since March 2020, with many cases of Covid but none serious - save one, who already had severe degenerative lung disease.

I had a coworker who complained about losing her sense of taste and smell after getting it. She was frustrated because it was several months after she was infected and nothing changed. I suggested she try taking Vitamin D and Zinc supplements and she said she'd give it a shot.

Two weeks later she said her sense of smell and taste came back.

My extended family has all been on 125mcg(5000IU) D3 daily for 12-16 years. Most of us got CCP Flu early on in 2020. All of us immediately upon experiencing symptoms took the prescribed megadose of D3 and all but one was done with it in 8-10 hours. My son required more like 24 hours. During the time we have been taking the D3 we have experienced no other instances of flu or colds.
